DUBAI - An Iranian-American man detained along with three journalists in Iran last week has been released, a source close to the individual said on Wednesday.
The United States has called for their release and a senior U.S. official said Washington was using "all appropriate channels" to make its concerns known to Iran.
"They were treated with respect, given food and water," said the source, adding that the man, who is the husband of one of the three detained journalists, was not tortured. Their names are being withheld at the request of the couple's relatives.
Still in detention along with the freed man's wife, who is an Iranian-American photographer, are Jason Rezaian, 38, an Iranian-American and Tehran correspondent for the Washington Post, and his wife Yeganeh Salehi, a correspondent for the United Arab Emirates-based newspaper The National.
The four were arrested in Tehran last Tuesday.
During a raid on the home of Rezaian and Salehi, security forces "ransacked their house and confiscated their personal items, including computers, books, and notes," according to the International Campaign for Human Rights in Iran, a New York-based human rights organization.
